Abstract

During this time, many politicians were political without using the Qur'an's values to fight. Quite often from them they commit political rape which is very tarnishing the essence of politics. In fact, they were born from Rahim political party political parties. By Karen, it is time for Islamic politicians to re-understand, interpret and implement the Qur'an-based politics, based on the Sunnah of the Prophet and based on the sunnah of friends and follow ulamak whose knowledge is connected to the prophet and his heart contains Allah, the mind of the Ummah.

Abstract

The automatic voltage regulator (AVR) is a major component in generating electrical energy. To improve the performance of the AVR system, controlling the proportional integral derivative (PID)is needed because it has a simple structure, is very strong in system variations, and easy to understand. The main problem for the PID controller is determining the appropriate parametervalues for the values of the proportional constant (Kp), the integral constant (Ki), and the differential constant (Kd) to obtain the optimal transient response. In the conventional methodbased on trial and error, a more efficient method is needed, namely Particle Swarm Optimization (PSO), an optimization method based on a flock of bird population. The criteria the minimum errorintegral used as a fitness function in the PSO is the integral of time multiplied by squared error (ITSE). The parameter values used must meet the stability requirements, namely the stability characteristics of the Root Locus. PID control has a significant impact on the plant, this can be seen from the results that have a good level of stability. As for the criteria using the PSO-ITSEalgorithm has a better transient response. In finding these values and analysis using the Matlab software tools.Keywords:AVR, PSO, ITSE, Root Locus. transient response, Matlab

Abstract

In coal mining, to check the pH content of water in liquid waste from coal mining, mining workers mostly use the conventional method, namely by periodically measuring using a digital pH meter or litmus paper. Manual pH reading system makes handling slow. Based on these reasons the research designed a device that can monitor the pH value, the working principle of this tool is that the pH electrode is inserted into the sample solution and then the electrode detects the sample solution and will change the electrical signal where the output will be amplified by an amplifier circuit in the form of an analog voltage and will be converted. by Arduino Uno, analog data is converted into digital data or ADC (Analog To Digital Convertion) so that the results will be displayed on an LCD that is equipped with I2C. And this tool is also equipped with RTC (Real Time Clock) so that it can display the time when data collection on the pH level of the waste. The tool that is designed has an error percentage of the pH meter manufacturer of 0.4969%. By using this tool the authors conclude with 0.4 grams of lime (CaO) on the prototype or 480 kg in real conditions with a ponds area of 600 m3 can reduce the voltage output on the ph sensor from 3.25 V to 2.56 V so that the pH value increases. from 2.73 to 7.61 in pond 4 or dump ponds.
